How are reflecting telescopes different from refracting telescopes?

• Reflecting telescopes need light sources; refracting telescopes don't

• Reflecting telescopes magnify objects; refracting telescopes minimize them

• Reflecting telescopes use mirrors to collect light; refracting telescopes use lenses

• Reflecting telescopes use mirrors to collect light; refracting telescopes use lenses

How many lenses are found in the simplest telescopes?

• one

• two

• three

• four

What part of a reflecting telescope would you measure to find the aperture?

• the eyepiece

• the body

• the large lens

• the mirror

What can you infer about a telescope with a large aperture?

• Its images are brighter and clearer than other telescopes

• It can magnify things further away than other telescopes can

• It can magnify smaller objects than other telescopes

• Its eyepiece is much smaller than other telescopes

A telescope that can enlarge images from very far away has high:

• aperture

• resolution

• magnification

• definition

Which of the following is a type of simple telescope?

• 
• 
• 
• 

Why is the Hubble telescope located in space?

• So it can be closer to the stars it magnifies

• So its images aren't distorted by Earth's atmosphere

• So it can emit radio waves

• So it can be operated by astronauts
